[0024] The auxiliary connection mechanism 200 is installed on the outside of the interface 110 of the driver body 100, and the interface 110 is connected to the intelligent control encoder. The auxiliary connection mechanism 200 includes a locking member 210, and the locking member 210 is sleeved on the outside of the interface 110. A locking positioning member 220 is provided on the outside of the locking member 210.

[0025] See also Figure 2 and Figure 3 The locking member 210 includes a limit plate 212, on which strip limit holes are evenly spaced apart. A telescopic rod 214 is arranged above the limit plate 212. The bottom of one end of the telescopic rod 214 is fixedly connected to a limit rod 213. The limit rod 213 slides in the strip limit hole of the limit plate 212. The other end of the telescopic rod 214 slides in a limit manner and passes through the side wall of the positioning ring plate 217. The positioning ring plate 217 is rotationally mounted on the limit plate 212.
